What version of Java needs to be ran on an fiber switch Brocade 8/24

What version of Java needs to be ran on an fiber switch Brocade 8/24? Hi have 2 Brocade 8/24 and up until this week we were able to access the swithces by web broswer IE10 and Chrome. I think there may have been an automatic update of Java. Please advise
